MOTOR-VEHICLE.

To all whom it may concern:

Be it known that I, MILTON TIBBnTTs, a citizen of the UnitedStates, and resident of Detroit, Wayne county, State of Michigan, have invented certainnew and useful Improvements in Motor-Vehicles, of which the provide means for supporting a wind shield sash so that it may be slightly raised from the edge of the support upon which it rests and then be adapted to swing clear of the support to leave a clear space above the support. I

Another object of the invention is to pro- Vide means for automatically guiding the wind shield sash in its'various movements of being lifted oil" of the supportand into a positionto provide a clear space- Another object of the invention is to provide automaticrmeans for moving the two sashes of a wind shield outof line at the commencement of the swinging movement done of. the sashes in. changing from its closed to its open position.

Other objects of the invention will: appearfrom the following description taken in connection with the drawings which form a part of this specification and in which V Figure 1 is .a rear elevation of an illustrative form of windshield embodying this invention; I V

Fig. 2 isan edge View of-the windshield shown in Fig. 1, looking toward the left hand end. of Fig. 1 and showing'the sash in; raised position infull' lines and in lowered position in dotted lines;

Fig. 3 is an enlarged detail'edge view also looking inward at the left hand end of the wind shield shown in Fig. 1 and showing the upper sashmoved out of alinement with the lower sash.

Fig- 4-is a view similar .to Fig. 3 except. that the upper sash of the: wind shield has beenlowered to' a position'at the rear of the lower-sash; g Y 5 is a detail-vertical section on the line w-ar; of Fig. 1,-and Fig. 6 is an en v Specification of Letters Patent.-

larged detail edge view of the right hand end of the wind shield shown in Fig. 1, showing the sashes in alinement.

In the drawings t represents the lower sash or supporting part of a wind shield and 5 is the upper movable sash, these sashes when in normal or operative position being in line one above theother. The lower sash may, if desired, be braced as by the brace rods '6.

As shown, the sash 5 rests with its full weight upon the upper edge of the lower sash or supporting part l and these meeting, edges of the two sashes may be made to incline forwardly and downwardly as shown at 4' and5 in Figs. 3 and5. The exact shape of these meeting edges is not material except that the highest part of the edge of the support should be aboveand rearwardly of the lowest part of the edge of the sash 5 so that water striking the upper sash will pass over the joint and not through it.

, In order that the abovedescribed form of water tight joint may be used between the meeting edges of the upper sash and the supporting part, the present invention contemplates a supporting means for the upper sash that will permit it to be lifted bodily to clear the upper edge of the supporting part 4: and then moved .to provide a clear ventilating space above the supporting part of the wind shield. In the form shown the upper wind shield sash is raised slightly to clear the edgeof the lower sash and rearwardly out of line with the lower sash and then it is lowered by a relative endwise motion of pure translation in a circular path. One end of the two sashes is connected by a link arm 28 pivoted to the lower sash at its top at 29and extending at an inclination and pivoted to a bracket 30 on the upper sash. At the other end of the sashes a link arm 81 is pivotally connected to the upper sash at 32 and is pivotally connected at its lower end to a bracket 33 extending outwardly from the top of the lower sash, thus making the arm 31 stand at an inclination parallel to the arm 28. This inclined arrangement of the link arms permits the upper sash when moved to the right in Fig. 1 to be automatically elevated above the'lower sash during the first part of the swinging operation while being maintained constantly in a ver i 1 5 clined surface 36 against :which bears a ni ulatedby the handles 16.
